Answer: 14
Explanation In this series, each number is repeated, then 13 is subtracted to arrive at the next number. Rule = (1st number) (1st number) (1st number - 13 = 2nd number) (2nd number repeat) (2nd - 13 = 3rd number) (3rd number repeat).... The series is 53, 53, 40, 40, 27, 27... (53),(53 - 13 = 40), (40), (40 - 13 = 27) (27), (27 - 13 = 14), (14)... So the answer is 14.
Answer: 232
Explanation The solution in the image explains the pattern clearly. Let's break it down: Step 1: Identify the pattern. Difference between 466 and 341 = 125 Step 2: Multiply the difference by 2. 125 × 2 = 250 So, 250 is the correct number inside the parentheses after 341. Step 3: Apply the same pattern to find the missing number. Difference between 398 and 282 = 116 Step 4: Multiply the difference by 2. 116 × 2 = 232 So, the missing number in the sequence is 232 .
Answer: (a+b)/2
Explanation Let, a and b two given numbers. Let, A 1 , A 2 , A 3 . . . . . . . . . . . . . A n be Arithmetic means between a and b. a , A 1 , A 2 , A 3 . . . . . . . . . . . . . A n , b are in A.P. a + A 1 + A 2 + A 3 + . . . . . . A n + b = ( 2 n + 2 ) ( a + b ) (first term is =a, last term=b, number of term=n+2) A 1 , A 2 , A 3 . . . . . . . . . . . . . A n = 2 ( n + 2 ) ( a + b ) − ( a + b ) = ( a + b ) [ 2 n + 2 − 1 ] = ( a + b ) [ 2 n + 2 − 2 ] = n ( 2 a + b ) SH14-8-2023
Answer: 19
Explanation The pattern of the sequence appears to be a alternating addition and subtraction of numbers: 14 - 5 = 9 9 - 4 = 5 5 + 16 = 21 21 - 13 = 8 8 + 5 = 13 13 + 15 = 28 28 - 19 = 9 So, the next number in the sequence would be: 9 + 10 = 19
Answer: 360
Explanation Each term is multiplied by consecutive numbers (2, 3, 4, 5) . So, the missing term = 72 × 5 = 360 .

Answer: 28
Explanation 28+6= 34 34+6= 40 40+6= 46 46+6= 52 52+6= 58
Answer: 56
Explanation The pattern alternates between multiplying by 2 and subtracting 8 : 14 × 2 = 28 28 - 8 = 20 20 × 2 = 40 40 - 8 = 32 32 × 2 = 64 64 - 8 = 56
